The hub of a beveled gear 25 is rotatably mounted in the bearing member [5, which hub is provided with a non-circular opening 26 to r'eceive the correspondingly-shaped end 21 of the shaft so that rotation of the hub of the gear a certain range of relative movement to and from the collar 33 due to the fact that the rod 58 will slide freely through the flange 59, nevertheless the amount of separation of collars 32 and 33 will be limited when the head 60 of the rod 58 strikes the flange 59, as shown in Fig. 3. If, at this time, further movement of the collar 32 toward the left takes place, it will tend to also draw the collar 33 toward the left.

A spring 62, mounted on the pivot 54,-acts on the depending portion 59 of the collar 32 to urge the latter toward the left as shown in Figs. 2 to mounted upon the shaft, are collars 32 and 33.

Collar 32 is provided with internal screw threads 34 designed to operatively engage threaded portion 3| of the shaft 20 and is also provided with an internally smooth portion 35 designed to slide over these threads.

The collar 33 is provided with internal screw threads 36 intermediate its length and is provided at one side of these threads with an internally smooth bore 37 designed to slide over threads 3| and at the other end with a smooth bore portion 38 designed to slide over the reduced end 39 of the bearing member l5, so that the outer edge of the collar 33 may, in some positions of the parts, abut against a ber l5.

Secured to the window sash, adjacent the supp rting plate I3, is a'second plate 42 which may be held in place by the screws 43 and, as shown in Fig. 8, the sash is slotted or cut away below this'plate to receive certain connecting members which-connect the operator parts previously describedwith the sash, which previously described parts, it will be recalled, are mounted on the frame. v

- One of these members comprises a link 44 pivoted to the'plate l3 at 45 and to the plate 42 at 46. In addition, an arm 41, which is carried by the collar33, is provided with'a rearwardly curved portion, the end of which is pivoted at 48 to the plate 42. 5 As shown in Fig. 4, the collar 32 is provided with a vertically projecting boss 58 which extends through a slot 5| provided in the plate I 3, the end of this boss being loosely received in an elongated opening 52 in a lever 53 pivoted to the plate l3 at 54. As shown in Figs. 2, 3, and 6, for example, the lever 53 is of curved formation and the outer free end thereof extends toward the window sash so that in certain positions of the latter it may enter the slot below the plate 42 and con-- tact witha wear-plate 42 secured to the plate 42 and extending at substantially right angles to the latter plate or in a vertical direction. The outer end of the lever 53. isalso designed to engage behind a pin or screw 55 screwed to the window sash through the plate 42 and serves to draw the sash tightly to closed position.

Secured to the collar 32 is a lug 51, to which is fixed a rod 58 passing loosely through a flange 59 upstandingly mounted on the arm 41 secured to the collar 33. The free end of thi rod is provided with a head 60 which is too large to pass through theopening in the flange 59. It will be obvious with this construction that, while as shown in Fig. .2 the collar 32 will be permitted shoulder 40 on the bearing mem- 4 so that, when this collar has been moved to a position in which its threads 34 are disengaged from the threads 3|, it will tend to remain in such position until positively moved in opposite direc- 'tion.

As shown in Fig. 1, the shaft 29 is rotatably carried by the frame of the window and carries, intermediate its ends, a beveled gear 64 which is non-rotatably mounted on the shaft and which is supported by means of a plate 65 in which it is rotatably mounted, this plate being, in turn, supported by a bracket 65 secured to the window frame. A shaft 61 is rotatably mounted in the bracket and secured to this shaft, is a gear 68, the teeth of which mesh with the gear 64. The shaft 61 may be rotated by the crank 69.

The operation of my device may now be briefly described.

" When the crank 69 is rotated, the shaft 29 will likewise be rotated, thu serving to rotate the gears 28 at the upper and lower ends of this shaft and actuate the operators. As the action is identical at the top and bottom of the sash, it will. be necessary to describe the the operators only.

The parts are shown in Fig. 2 of the drawings in the position which they occupy when the window is closed. In this position, it will be apparent that the collar 33 abuts the shoulder on the bearing member l5 and that the threads 36 have passed beyond the .point at which they would engage the threads 3|. At this time, therefore, rotation of the shaft does not directly effect movement. of the collar 33. It does, however, ef-

' fectmovement of the collar 32, for, as seen in Fig.

2,,the threadsof this collar are engaged with the threads 3| of the shaft 20. Therefore, rotation of the shaft 28 in the proper direction serves to move thecollar 32 toward the left which tend to swing the lever 53 in a clockwise direction about its pivot 44. The free curved end of this lever is moved outwardly against thewear plate 42 and thus tends to push the sash outwardly about the pivot 48 and the sash moves from the position shown in Fig. 2 to that shown in Fig. 3, the rod 58 sliding freely through the flange 59, and it will also be noted that the collar 33 has moved to the left to a slight extent, thus permitting the pivot point 48 to move to a slight extent to permit th sash to swing.

, At this time, the parts are in the position shown in Figs. -3 and-4, and it-will be noted that the collar 32 has been moved substantially to theaction of one of V threadsdl: a; d me edteward the/left f em ,the head so of the rod 58 with the flange as, the

, lever 53 in an anti-clockwisedirection. As shown exerts a pull upon the sash'by means ofthis and the sash willbepositively and firmly drawn 1 against the frame at both top and bottom.

Atthis time,jdue to the engagement of ngii collar32 is moved toward the right to engage its threads 34 with the threads 3 I, which occurs substantially at the time the threadsfof the collar 33 reach the righthand end of the threads 3|. The collar 33 is therefore free of the threads 3| and the collar 32 is picked up and moves the in Fig. 6, this movement of the lever effects engagement of its free end behind the pin or screw 55, and continued movement of this lever screw to drawit to closed position. During this latter phase of the closing movementofthe sash, the collar 33 movesfrom the position shown in Fig. 6 to its fully closed position shown in Fig. 2
